Hi, This is a cross-post from friendlyarm.com forum - no response so far, maybe will be more lucky here. I'm using this screen with M3 on debian. How can I change screen brightness (backlight) or how can I switch the screen completely (not blank it - as I see, the backlight is still on)? Using /sys/ filesystem or any other programmatical method. Thanks Kuba

Hi，Command line input: echo 15> /dev/backligh When the 1-127 is sent to the backlight device, you can adjust the brightness of the backlight; 127 of which is the brightest, usually about 15, You can see some of the images in the dark, for 1-15, the basic black piece. When greater than 127, will be treated as a 127, also is the brightest.
